strstr

(PHP 3, PHP 4 )

strstr -- Find first occurrence of a string

Description

string strstr ( string haystack, string needle)

Returns part of haystack string from the first occurrence of needle to the end of haystack.

If needle is not found, returns FALSE.

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

Замечание: This function is case-sensitive. For case-insensitive searches, use stristr().

Пример 1. strstr() example

$email = 'user@example.com';
$domain = strstr($email, '@');
print $domain; // prints @example.com

Замечание: If you only want to determine if a particular needle occurs within haystack, use the faster and less memory intensive function strpos() instead.
